Recover lost output
Solar Panel Cleaning
A dirty array simply generates less. Dust, pollen, bird fouling and moss along the panel edge all reduce the light reaching the cells, and shading a single cell drags down the whole string.
Solar panels on a commercial roof being cleaned by Lanes Ltd
Cleaned the way manufacturers ask for
We clean panels with filtered pure water and a soft brush — no detergents, no abrasives and no high-pressure jetting. Pure water carries no minerals, so panels dry without the mineral spotting that tap water leaves behind, and there is no chemical residue to attract more dirt or run into the ground around a solar farm.
Arrays we clean
- Commercial rooftop arrays on offices and industrial units
- Agricultural building and barn roof installations
- Ground-mounted arrays and solar farms
- School, care home and public building installations
- Domestic roof panels
Reached safely from the ground
Most rooftop arrays can be cleaned with a water-fed pole from ground level, which avoids anyone walking on the roof or standing on the panels. Larger or obstructed installations are cleaned using powered access with IPAF-certified operators.
How often is worth it
An annual clean suits most installations. Arrays near arable land, livestock buildings, busy roads or heavy tree cover accumulate faster and are usually worth cleaning twice a year — the recovered generation typically outweighs the cleaning cost.

Solar Panel Cleaning: your questions answered
Does cleaning solar panels really improve output?
Yes. Soiling, bird fouling and edge moss block light reaching the cells, and because panels are wired in strings, shading part of an array reduces output disproportionately.
What do you clean the panels with?
Filtered pure water and a soft brush only. No detergents, no abrasives and no high-pressure jetting, so there is nothing to damage the panel surface or seals.
Do you clean solar farms as well as rooftops?
Yes. We clean everything from a handful of domestic panels to ground-mounted commercial arrays and solar farms across Lincolnshire and Rutland.
Will anyone need to walk on my roof?
Usually not. Most rooftop arrays are cleaned from ground level with a water-fed pole; where that isn't possible we use powered access.
How often should panels be cleaned?
Annually for most sites. Arrays near farmland, livestock buildings or heavy tree cover benefit from twice-yearly cleaning.
